A Look at the Proxxon Motorized Angle Polisher
Last issue, I wrote about Adam Savage restoring the yellowed plastic cover of a vintage Nagra IV-S audio recorder. He ended up using a combination of a 12% hydrogen-peroxide bath and stages of a polishing compound to bring the cover back to its former glory. In this video, he talks about the Proxxon motorized angle polisher he uses while restoring the faded and scratched plastic dome on a spacesuit helmet replica and extolling the virtues of the tool.
Paint Coatings: The Great Weapon Against Rust
Grady of the fantastic Practical Engineering channel continues his series on corrosion engineering by looking at one of the great weapons wielded in the war against steel rust: paint (or more accurately paint coatings).
Next-Level Oscillating Multi-Tool Tips
Wow. James of Stumpy Nubs always brings the goods, but I learned so much from this video on improving one’s use of an oscillating multi-tool. I just recently bought my first cheap oscillating tool (to see how I like it) and am just beginning to learn how to use it properly. Even if you’ve had an oscillating tool for a while, I bet you’ll learn something here. How to angle your plunge cuts, pre-scoring cuts, holding onto the blade for better control (yes, it’s safe), using semi-circular blades for making straighter lines, so much more. Lots of tips for cutting metal with an oscillator, too. And, James has a good recommendation for an inexpensive blade assortment.
Quick ‘N Dirty Aluminum Casting
In this Daniel LupienYouTube short, he shows you how easy it is to create a simple sand mold and cast it in aluminum. All you basically need is a chunk of aluminum, a crucible and tongs, a source of heat, some kinetic sand (or regular casting sand), and something to press into the sand to create the mold.
No-Cost Stud Finder
When my wife and I moved to our new digs in Benicia, CA last fall, I needed to install a swivel-arm wall mount for our TV. I simply used a 1″ disk magnet I had on-hand to locate the stud. No fancy stud finder needed. In this Becky Stern tip, she shows the method of using a string and a magnet. Easy peasy. If you’re uncomfortable with this method and want to make sure to find the center of the stud and locate (and steer clear of) any wire runs, pipes, etc., sophisticated imaging scanners can be had for under $30.
Fixing a Leaky Faucet with a Ten Dollar Tool
We know that professional plumbing doesn’t come cheap. Doing your own basic maintenance and repairs may seem intimidating, but it shouldn’t. Jobs like clearing a trap, changing a toilet float assembly, or replacing faucet washers are relatively simple and easy. Years ago, I changed a toilet float kit. It was easy (after getting the very frozen-in old assembly out). And, I felt like I’d accomplished something and saved myself over $100. The replacement kit was $15.
Mark Frauenfelder of Cool Tools recently replaced the rubber washer in his shower. He writes in Recomendo: “Our shower head was leaking, even after I replaced the rubber washer. YouTube informed me that I had a scarred valve seat, which is the brass ring that’s supposed to form a tight seal against the washer. I bought a reseating tool for about $10 on Amazon, which smooths the surface of the valve seat. It worked, and saved me a $150 plumber visit.”

Shop Talk
Reader Art Elliott shares this tip:
“My fav pencil is the tri-conderoga. It’s the best of both worlds. Three sided, so it doesn’t roll away, and thinner than a regular carpenters pencil, so you get sharper lines, but it’s also thicker than a regular pencil, so the lines are still nice and thick. My family got me a pack for Father’s Day and they’re my go-to in the garage.”

On the issue of CA glue curing accelerated by water or baking soda or baking soda and water, reader Josh Martin writes:
“Setting CA glue with water makes an inconsistent, often crumbly consistency to the set glue. Baking soda improves on this, but nothing works as well as accelerator (or just time).”
In reference to storing CA glue in the freezer, reader KX4WD enthuses:
“The money I could have saved on super glues over the years with this storage tip!”

Cool tools really work.
A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful. We post things we like and ignore the rest. Suggestions for tools much better than what is recommended here are always wanted.
This two-sided page contains the wisdom of an entire book on how to write better. Nay, it distills an entire shelf of the world’s greatest writing manuals (and I have them all). After 30 years as both a writer and editor I can’t think of much I would add to these 50 short tips. This PDF is now my favorite guide to writing well. You can print it out for free. If you want its pithy reminders fleshed out with more examples, see the book form, or the website. But the free tip sheet itself — one paper printed both sides — rewards a quick review anytime you get down to serious writing.. – KK
There’s an emerging new media I use more and more: an online summary of a conference. Known as liveblogging, it presents a synopsis of each presentation, talk-by-talk, in nearly real time. This saves you time and money traveling to distant cities, and suffering through introductions and equipment failures. At its best, reading the liveblog can be better than attending the talk. All the chaff has been winnowed, and almost every talk captured. (Most conference attendees don’t even get to every talk.) Video recordings of conferences are becoming more popular, but a good liveblog is much quicker to scan and digest. But at its worse, a liveblog will offer little more than snarky comments about the speaker.
At the creation end, you need some skills to separate the best from the worst. Ethan Zuckerman, of Geek Corp, is one of the best conference bloggers alive. He teamed up with Bruno Giussani, another star liveblogger, to produce this free short 6-page PDF booklet on how to blog a conference with effectiveness. When you blog a conference it forces you to pay attention. My first book Out of Control began as an online blog of every talk at the first Artificial Life Conference (although no one called it blogging in 1987). The requisite focus of summarizing each talk clarified many ideas for me, and the response to the “blog” of the conference encouraged me to write a book. Other livebloggers find the same. They listen harder, and remember more.
Get good at this and you have a free pass to many high-priced conferences. Organizers are increasingly looking for first-rate livebloggers to generate press and future attendees. Or, like Ethan you can generate your own audience who follow you because your liveblogging skills. – KK
It’s relatively easy to blog good and great speakers: They follow a narrative path through their talks and speak at a pace the audience can understand. It’s harder to blog inexperienced speakers(because they may be too technical, confusing, fast, etc.) and multispeaker panels (because the discussion can take many different unstructured turns). But you don’t need to transcribe the whole talk, you need to capture the gist of it. A 20-minutes talk can often be summarized in a 20-lines post.
Always remember that what you’re writing will be read by people who weren’t in the room, so they haven’t seen the slides, the video, or the gesture. Hence, you have to compensate for the lack of context. Don’t be afraid to create a narrative by saying “He shows a slide with data on …” or “She walks on stage carrying a big suitcase” or “He shows a YouTube video” etc. And if the speaker shows a YouTube video, or a picture, remember that you’re online: Open another browser window, go to YouTube, find that video, and link to it; or go to the speaker’s website, find that picture or another similar or related item, and link to it (or republish the picture within your post). Yes, this requires effective multitasking. It’s at the root of conference blogging.
Conferences usually give out a program ahead of time. Use it to prepare for blogging: Do a quick Google search for each speaker, and save (in the same text file) links to their sites, blogs, and the institutions they’re affiliated with; write a one-or-two-sentences “biography” for each; and for the speakers you’ve never heard of, try to get a general sense of who they are and what they do. To write the mini-biography, use also the speaker information distributed by the conference organizers (booklet, website, etc.). For the key speakers, save a picture on your laptop (from their websites) and pre-format it for Web use, in case you will need it. If you prepare sufficiently, you’ve got the first paragraph of each post almost written ahead of time.
This is the best thesaurus there is. It supplies more synonyms, analogs, parallels, equivalents and comparable words in English than any other source, online or off. No other thesaurus comes near to it for completeness or breadth. Compiled in dictionary form, like the one in your word processors, there’s no index or cross-referencing. Just look up a word, any word, and it proceeds to overwhelm you with alternative choices (a total of 1.5 million synonyms are presented in 1,361 pages), including short phrases and only mildly related words. Rather than being a problem of imprecision, the Finder’s broad inclusiveness prods your imagination and prompts your recall.
Its single downside, however, is a major frustration: it is not available digitally, in a form compatible to the way most people write these days. It should live on your computer in a pull-down option, or plug-in for Word or the like. I’m totally baffled why it is not. As it is, it’s a huge fat book — a great book! — sitting within arm’s reach when I write, but not near enough for the power that it offers. – KK
